IA structure (sometimes called a site map) is a map of all the key nodes of a site (e.g., pages or screens) and the relationships between them.In service- design lingo, navigation is frontstage (i.e., visible to users). Navigation is a series of UI elements (menus, links, breadcrumbs, and accordions) that show the user which page or screen they are currently viewing and where they can go.A content model shows the relationships between different content types. The taxonomy is a separate hierarchical metadata structure that controls the specific terms (i.e., concepts) used to describe the content within the IA structure. The 4 types of organization models in IA: The navigation is a user-visible partial view of the full underlying IA structure, which isn’t visible to users. 4 Types of Organization Models in IAĪdmittedly, information architecture can be a confusing discipline - there are many different types of abstract organization models that all seem quite similar but map out different things. The major four organization models are listed below: It’s important to note that a taxonomy is different from the navigation structure that users interact with and from the underlying IA structure. Each time we tag content using a taxonomy, we must follow some ground rules about which terms to use and how those terms relate to other terms. Taxonomies are essentially controlled tag systems - while each piece of content will have a set of taxonomy terms attached to it, content creators cannot define their own terms. An example taxonomy: each piece of content on a website would be tagged with one or more of these terms to make it easy for the backend to direct the user to appropriate, related content. The idea is that the taxonomy defines a limited set of terms for describing our content in the background content creators must attach them to any new piece of content, with no ability to expand this vocabulary on an ad hoc basis.ĭefinition: A taxonomy is closed list of acceptable terms that are arranged hierarchically and are used to describe and classify content. Taxonomies are what information-science professionals call controlled vocabularies - planned, prescriptive ways of adding descriptive metadata to content so that it can be retrieved effectively. What is a taxonomy and why does it matter for UX practitioners? In our UX Conference Information Architecture course, I often get asked what a taxonomy is, how to build one, and how it fits into the larger landscape of information-architecture (IA) work.
